Verdict
The clearest difference is price: Geotag Alpha at Free against Lumy's $7.99. Geotag Alpha also leads on review sentiment (89% vs 79%). Lumy's advantage is update cadence (every 3 days vs every 5 weeks) and ratings volume (2.5K vs 26). On rating, ads, in-app purchases and monetization model there is nothing between them.

Geotag Alpha is free to download; Lumy costs $7.99 up front. Lumy sells 3 one-off in-app purchases and Geotag Alpha sells 8 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
Geotag Alpha holds the better App Store score, 5.0 against 4.8.
